cfgadm -c unconfigure disk 时蓝色 LED 指示灯没有亮起 (22724487)

在将 cfgadm -c unconfigure 命令用于 12 磁盘底板或 24 磁盘底板上的磁盘驱动器时，表示“可以移除”的蓝色 LED 指示灯没有亮起。

解决方法：使用 fmadm set-indicator 命令点亮对应的蓝色“可以移除”LED 指示灯，这样可以定位取消配置的磁盘。例如，要取消配置 HDD3：

1. 找到要移除的驱动器的设备路径。

       # diskinfo D:devchassis-path
       c:occupant-compdev ----------------------------------  ---------------------
       /dev/chassis/SYS/HDD0/disk          c0t5000CCA02D0F9E94d0
       /dev/chassis/SYS/HDD1/disk          c0t5000CCA02D102F60d0
       /dev/chassis/SYS/HDD2/disk          c0t5000CCA02D100F28d0
       /dev/chassis/SYS/HDD3/disk          c0t5000CCA02D0F6C44d0
       /dev/chassis/SYS/HDD4/disk          c0t5000CCA02D0F6DBCd0
       /dev/chassis/SYS/HDD5/disk          c0t5000CCA02D10366Cd0 
       ....
     

2. 检查驱动器状态。

       # cfgadm -al Ap_Id
       Ap_Id            Type     Receptacle   Occupant     Condition 
       /SYS/DBP/NVME0          unknown    empty     unconfigured unknown
       ...
       c3::w5000cca02d0eda3d,0  disk-path  connected    configured   unknown 
       c3::w5000cca02d0f5ca1,0  disk-path  connected    configured   unknown 
       c3::w5000cca02d0f6c45,0 disk-path  connected    configured   unknown 
       c3::w5000cca02d0f6dbd,0  disk-path  connected    configured   unknown 
       ...
     

3. 取消配置该驱动器。

       # cfgadm -c unconfigure c3::w5000cca02d0f6c45,0
       # cfgadm -al
   
       Ap_Id                    Type       Receptacle   Occupant     Condition 
       /SYS/DBP/NVME0           unknown    empty        unconfigured unknown
       ...
       c3::w5000cca02d0eda3d,0  disk-path  connected    configured   unknown 
       c3::w5000cca02d0f5ca1,0  disk-path  connected    configured   unknown 
       c3::w5000cca02d0f6c45,0  disk-path  connected   unconfigured   unknown 
       c3::w5000cca02d0f6dbd,0  disk-path  connected    configured   unknown 
       ...
     

4. 打开该驱动器的“可以移除”指示灯。

       # fmadm set-indicator /dev/chassis/SYS/HDD3/disk ok2rm on    
       The indicator (ok2rm) has been turned on. 
     

5. 确认“可以移除”LED 指示灯已点亮。

       # fmadm get-indicator /dev/chassis/SYS/HDD3/disk ok2rm
       The indicator (ok2rm) is set to on. 
     

6. 现在可以安全地移除驱动器了。
